Okay this is once again talking about the server side. I think you've
confused the server side issue with the client side issue over and over.
I understand the admins complaining about this on the server side. But
the reason the passwords are stored in clear text is because of the
authentication design that Greg Hudson chose for svnserve. This only
applies to svnserve and only if you're not using ssh. The solution is
to either implement our own new authentication protocol that allows
plaintext passwords (especially since SSL is now in the pipe for
svnserve) or implement something like digest authentication that apache
As Karl pointed out later in the thread, implementing rot13 isn't going
to get rid of the emails. It isn't going to make things more secure.
If you think someone walking past your monitor is going to memorize a
password why can't they memorize the rot13 version of it and walk back
to their workstation and do: echo foo | rot
Adding a trivial cipher does not change the problem, it just hides it.
Greg suggests some excellent solutions to the problem in the short and
long term in his posts.
However, the client side problem is much trickier. In order for caching
to work with all authentication protocols we must cache the plaintext
To this end I agree, I'm tired of hearing this complaints. So I'm
taking it upon myself to fix these issues. This means I'll be working
on svnserve to make it support additional authentication methods and
implementing svn-agent for the client side.
